Fishing Reports

Jimmy's All Seasons Angler / Fishing Reports (Page 99)

Henry’s Fork 8-23-14

From Last Chance to Pinehaven terrestrial patterns will bring the best daytime action.  Fish these around overhead cover.  For the mayfly enthusiasts tricos and speckled duns are emerging, so their dun and spinner patterns are a must, especially in the morning. In the Coffee Pot area terrestrial patterns are best with caddis life cycle patterns doing well in the evening.


Small Streams 8-23-14

Change your fly-fishing strategy a bit for any small stream that has an increase in flow because of our continued rainy weather. Increased flows tend to wash more worms, grubs, etc into the stream making it easier for fish to get these on the subsurface drift than going to the surface for floating food. Put a few San Juan worms in your fly box, or if you rather not, include some small wooly bugger types. I did better on Robinson Creek earlier this week with (OK, I’ll admit it!) with San Juans than with the dries I love to present.  Certainly water levels will drop to normal, and the dry fly fishing that so many enthusiasts enjoy will return soon.


Still Waters 8-23-14

The cool, wet weather we currently have is just what is needed to bring still water fishing back to good times. Water levels are down in most reservoirs, so shallow water benefits the most.  Midge pupa patterns under an indicator are working well, for example, on deeper parts of Daniels Reservoir. Deep is where the coolest water is, anyway. Another tip: if damselflies are in the air, that means they are still emerging, so  be sure to have nymph and adult patterns in that fly box. Such has been the case with Springfield Reservoir where fishing wet or dry damselfly and speckled dun patterns in the channels around weed beds and around submerged springs has been productive this summer.


Southwestern Montana 8-16-14

Big happening on a lot of streams is appearance of spruce moths. The Gallatin and the Big Hole have famous hatches, but any stream flowing through fir or jackpine forests will have significant hatches of these insect that we are not fortunate to have, except that they attract trout. Best fishing for them is after morning sun warms them enough to fly and mate.  Hebgen Lake gulper action has been a bit spotty as of late, but late in the day fishing on the river below has been good when spinner falls or caddis swarms take over.  Want a treat with a lightweight system? try the West Fork of the Madison River. You can drive for miles up this stream to catch eager browns, bows and  cutts. Nothing big, for sure, but great action in the riffles, runs and pools.  It’s another great choice for taking an entry level or physically challenged person.


Yellowstone Park 8-16-14

Here’s a blanket statement for all Park streams with a higher gradient (ie: Gallatin River, Snake River, lower Lewis River, upper Gibbon River, Cave Falls area on Fall River): expect action with caddis life cycle patterns in the evening, spinners in the AM and again in the evening, and terrestrial patterns during daytime. Any day now, as we cool off, tricos will become important enough for fish to take notice on many streams and even still waters.  Be assured that as a result there will be many places in the Park that will offer great AM fishing.


South Fork 8-16-14

A quick note to say that the flow out of Palisades Dam was dropped from 10300 cfs to 10200 cfs two days ago. This small adjustment will not impact fishing.  But as Jimmy said recently, expect more flow reductions coming up out of the dam. Some will be significant, others like this one not important with respect to fishing action


South Fork 8-15-14

The South Fork continues to fish very well. We have benefited from cool water temperatures and some great overcast weather and rain showers. The flow dropped another 1,000 cfs earlier this week bringing the river down to 10,300 cfs at Irwin. We should continue to see additional drops in the flow as irrigation demand goes down.

Each drop in the water exposes more cobble and causes the wingless golden stone to emerge. The decreases are also making the riffles more defined and creating more riffles. We are seeing good hatches of pink pale morning duns during the day and caddis in close to dark.

The lower river below Byington has been productive with big hopper and chernobyl patterns. The riffle fishing has been good to which is probably due again to the cooler temperatures this summer. The morning water temps at Lorenzo have been cooler(58 degrees) than the upper river at (60 degrees).

We have been having good success fishing a pair of dry flies in the riffles even before the hatch starts. Try a #14 or 16  parachute trailed by a thorax pale morning dun, thorax pink albert or a parachute pmd spinner. Once the hatch starts and the fish start rising to the actual bugs be ready to change patterns from duns to emergers to nymphs and then maybe back to a dun.

In addition to caddis in the evening fish a #6-10 gold or purple bodied chernobyl against the bank and over the drop offs.



Southwest Montana 8-12-14

We hear that fishing is slowing down a bit on the Madison River, but not so on Hebgen Lake where morning gulpers are providing great fishing.  Other lakes in this area provide gulper fishing, and have nearby accommodations in the form of lodges or campgrounds.  Consider trying the north and south ends of Elk Lake or shallows along the west shore of Wade Lake for gulpers.


Yellowstone Park 8-12-14

Best tactic for almost all meadow streams here is presenting terrestrial patterns. The exceptions are the meadow reaches of the Madison River drainage where water temperatures are high enough to stress fish when being caught. But for Fall River Basin streams (Bechler and Fall Rivers, Boundary and Mountain Ash Creeks), Slough, Obsidian, and Soda Butte Creeks, and Lamar River, hopper, ant, and beetle patterns will bring your best chances for action. As I have mentioned in past reports, the humpy is a superb deerfly and horsefly pattern. Do not be on the stream without it!  Best still water action in the Park is, as usual this time of year, at Beula Lake where gulpers are active.  You can fish them from shore or from the float tube you backpack in. Small leech patterns will always get you chances for action there. If you do not want to do the two and a half mile walk to Beula, the two mile walk over flat ground to Riddle Lake gets you into the same action, albeit by smaller cutts. Fish the northwest corner of the lake from shore .
